Ok guess your a lucky one all 3 agreed, only one other person came close to agreeing mine was ok one... Out of many

So have you decided what cam you are going to use next? And if so, what do you feel the advantage is going to be over your current grind and how did you come to that conclusion?

I like that build recipe that CigRocket posted

Winter goals, except with iron heads

Yep..

I suggested a thread while ago that consisted of proven recipes for different sized motors. I.e: 502 cid do this get that. Didn't happen because no one wants recipes. For some reason everyone thinks their motor/ boat is unique and they need to reinvent the wheel.

Sure I believe in evolution and progress, but few have the time money and patience to be a Guinea pig.not pick on Tim but as a basic example.. How long have mistresses been around and how long have people been building 650-700 hp motors for them? Somehow I doubt Tim is the first one with those goals.

Imagine if he searched Oso before hand and found a recipe that hilly boater used to build a 700 hp 540 and that 3 others had copied the build with good results...

If that was readily available how many people would still be boating instead of selling their crap because they are tired of pouring money into it and spending their season trying to fix it instead of enjoying it....:

Probably something like this if a change is made..

Research mistress here with 650-700 hp you find like 2

Yes I do and did enjoy the boat all summer, every weekend besides 2, lots of fun and test and tuning , like joe said... Imagine if he gave up at guys telling him a blown 454 was a waste of time ...

I cant remember the exact details anymore but a local guy had a non stepped 27 fountain, he paid a employee or ex employee of sterling engines to build him a "strong" 540 as a side deal. He got motor back and stopped by w cam card and dyno sheet, this thing had hp peak somewhere north of 6500 or 7000, it was a solid that looked like it needed to be in drag car. But motor made 700 + hp. Gets it in boat, wont pull his new 28 pitch or his old 27 any faster than his 509, borrows a 26, nope, borrows a 24, boat would rpm a 23 or 24 into the high 70s/low 80s but was a miserable pos
It IS possible to go too big, seen it, guys name is Todd Kramer , hes a member here, dont remember his screen name though, but he may have posted the cam specs here at one time, i know it was like a .740 lift w something like 268/274 @.050 or bigger, BBX heads that were ported

Yup, on extreme side. Case of too much too late. ^^^

Another generic statement - if a boat struggles to get on plane with a 550ft/lb motor at it's planing rpm of say 2800rpm, going down to 530ft/lbs at same rpm from a bigger cam/heads/ and/or etc, willkick your azz.

If you don't need much throttle at all to get on plane, then you can sacrifice if you have too.

Thus the quickly mentioned bigger single i/o's vs lighter twins (vs heavier twins)....obviously Tim's is not a light twin.

What was the difference between a 496/375hp and 496/425hp , mag engine?
